摘要：

The concept that the first excited 0(+) states in N = 90 nuclei are not a beta-vibration but a second vacuum formed by the combination of the quadrupole pairing force and the low density of oblate orbitals near the Fermi surface is supported by the blocking of this collective mode in Gd-154 from coupling to the [505]11/2(-) single-particle quasi-neutron orbital in Gd-155. The coupling of this orbital to the 2(+) gamma-vibration in Gd-154 is observed since this coupling is not Pauli-blocked.
